Description

Technical Field

[0001] The present invention relates to the technical field of river sediment pollution treatment, and specifically relates to an in-situ deep treatment device for river sediment pollution and a using method thereof. Background Art

[0002] Aeration is a common technology for river water pollution treatment. However, most of the existing technologies are aerating in the water body or directly in the sediment. Aerating in the water body has little effect on the treatment and restoration of the endogenous pollution of the sediment. Directly aerating in the sediment easily disturbs the sediment, releasing the pollutants in the sediment into the water body, causing a short-term exacerbation of water pollution, increasing the turbidity of the water body due to the floating of suspended particles, which is not conducive to the assessment of the monitoring section. Directly adding microbial agents to the water body is costly, and due to the water flow velocity, the microbial agents are easily washed away by the water flow, and the time for the microorganisms to degrade pollutants is relatively slow, and a short-term stay is required.

[0003] Chinese Patent CN114380469B discloses an in-situ deep treatment device for river sediment pollution and a using method thereof. By setting a box body inserted into the sediment and treating the sediment in the selected area, the loss of microbial agents and the large-scale turbidity of the water body can be avoided. However, this device directly inserts the working components for aeration and discharging the agents into the sediment. However, for the common stones at the bottom of the river, as long as a part of the annular aeration pipe of this device is blocked by a stone, the whole cannot be inserted into the sediment, seriously affecting the aeration and microbial treatment effects. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides an in-situ deep treatment device for river sediment pollution and a using method thereof, which solves the problem that the existing device directly inserts the working components for aeration and discharging the agents into the sediment. However, for the common stones at the bottom of the river, as long as a part of the annular aeration pipe of this device is blocked by a stone, the whole cannot be inserted into the sediment, seriously affecting the aeration and microbial treatment effects.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An in-situ deep treatment device for river sediment pollution includes a winding mechanism installed on a ship hull and a treatment part for treating river sediment. The winding mechanism is connected to the treatment part through a pipeline. The treatment part includes a metal frame with an open bottom. A telescopic aeration component is fixedly connected through the top of the metal frame. An exhaust vertical pipe is fixedly communicated in the middle of the top of the metal frame. A waterproof electromagnetic exhaust valve is fixedly connected to the top of the metal frame. A counterweight component is arranged on the inner top of the metal frame.

[0006] The telescopic aeration assembly includes a plurality of groups of circumferentially distributed sleeves fixedly connected through the top of the metal frame. A telescopic pipe is slidably connected inside the sleeve, and upper and lower two groups of telescopic aeration pipes are rotatably connected between the bottom ends of adjacent telescopic pipes. An aeration branch pipe and a bacterial liquid injection branch pipe are fixedly connected inside the telescopic pipe, and the bottom ends of the aeration branch pipe and the bacterial liquid injection branch pipe are respectively fixedly connected to one end of the upper and lower layers of telescopic aeration pipes.

[0007] Preferably, the telescopic aeration pipe includes an outer pipe rotatably connected to adjacent two telescopic pipes respectively. An inner pipe is slidably communicated between the interiors of the two outer pipes. A first spring is abutted between the top end of the inner pipe and the top inner surface of the outer pipe. A plurality of fine holes are formed in the side surfaces of the outer pipe and the inner pipe. The aeration branch pipe or the bacterial liquid injection branch pipe is fixedly connected to the end of one side of the outer pipe.

[0008] Preferably, the bottom end of the telescopic pipe is conical, and the cross sections of the outer pipe and the inner pipe are both oval pipes.

[0009] Preferably, four layers of partition plates are fixedly connected inside the exhaust vertical pipe, and three sealed cavities are formed between the four layers of partition plates. The top ends of the aeration branch pipe and the bacterial liquid injection branch pipe are respectively communicated with the sides of the upper two cavities, and an aeration main pipe and a bacterial liquid injection main pipe with bottom ends respectively communicating with the upper two cavities are fixedly connected inside the upper two partition plates.

[0010] Preferably, the winding mechanism includes a main chassis. A winch, an aeration pump and a bacterial liquid supply pump are arranged inside the main chassis. One side of the main chassis is rotatably connected with a pulley through a bracket.

[0011] Preferably, the pipeline includes a winding hose threadedly connected to the top end of the exhaust vertical pipe. The aeration main pipe and the bacterial liquid injection main pipe penetrate through the winding hose and are respectively connected to the aeration pump and the bacterial liquid supply pump. Reinforcing support rings are uniformly arranged on the surface of the winding hose.

[0012] Preferably, a conical hole is formed in the center of the bottom partition plate. A sealing plug that has a gap with the side wall and can block the conical hole is slidably arranged inside the bottom cavity. A second spring is abutted between the top of the sealing plug and the upper partition plate. An exhaust port is formed in the side surface of the bottom cavity, and a filter cover is threadedly connected to the outer end of the exhaust port.

[0013] Preferably, the counterweight assembly includes support blocks uniformly and circumferentially fixedly connected to the middle and upper layers of the inner wall of the metal frame, and positioning blocks are fixedly connected to the tops of the support blocks.

[0014] Preferably, the counterweight assembly further includes a counterweight ring that can be placed on the support block. A notch adapted to the support block is formed through the upper and lower sides of the side surface of the counterweight ring, and a positioning groove adapted to the positioning block is formed at the bottom of the counterweight ring in a position misaligned with the notch.

[0015] The present invention also discloses a method for using an in-situ deep treatment device for river bottom sediment pollution, which specifically includes the following steps:

[0016] Step 1: Control the winding mechanism to release the pipeline, and then lower the treatment part so that it sinks to the bottom of the river and sinks into the bottom sediment;

[0017] Step 2: Start aeration and inject biological reaction bacterial liquid to carry out a biological bacterial liquid reaction on the polluted bottom sediment, and at the same time discharge the gas generated by aeration;

[0018] Step 3: After the treatment of the bottom sediment at this place is completed, lift its treatment part, move to the next place and then put it down again, and repeat Step 2 for reaction again. Beneficial effects

[0019] The present invention provides an in-situ deep treatment device for river bottom sediment pollution and a method for using the same. Compared with the prior art, the following beneficial effects are achieved:

[0020] 1. For the in-situ deep treatment device for river bottom sediment pollution and the method for using the same, the structure for inserting into the bottom sediment for aeration and injecting bacterial liquid is designed as a telescopic aeration assembly, and it is divided into multiple parts that can be independently telescoped and moved. Therefore, when it is inserted into the bottom sediment, even if a part is inserted onto a stone and cannot descend, it will not cause the whole to be unable to descend, and other parts can still be inserted for corresponding operations, improving the adaptability of the device.

[0021] 2. For the in-situ deep treatment device for river bottom sediment pollution and the method for using the same, multiple telescopic aeration pipes are connected to the telescopic pipe, which can form an annular structure. Thus, it can be expanded to a certain range for microbial treatment and aeration. At the same time, the telescopic aeration pipes are rotatably connected to the telescopic pipe and can also be telescoped themselves. Therefore, they can automatically change the angle and stretch along with the telescoping of the telescopic pipe. Even if some telescopic pipes are inserted onto stones and have different heights relative to other telescopic pipes, the telescopic aeration pipes can still form an annular structure. Moreover, the pipes for aeration and providing microbial agents are both protected by a winding hose, which is not only convenient for winding and unwinding, but also uses the reinforced support ring outside the winding hose to provide sufficient compressive protection to ensure the smoothness of the pipeline.

[0022] 3. For the in-situ deep treatment device for river bottom sediment pollution and the method for using the same, by setting a pressure valve composed of a partition plate, a sealing plug and a second spring in the exhaust vertical pipe, when the air pressure in the metal frame reaches a certain pressure value after aeration, the sealing plug can be pushed open for exhaust, and at this time, external water will not enter. At the same time, since the air is on the upper layer, the turbid sewage in the metal frame will not be discharged. Therefore, it can avoid polluting the external water, reduce the leakage of the bacterial agent, and also prevent the gas from lifting the metal frame and affecting the normal operation.

[0023] 4. The in-situ depth treatment device for river sediment pollution and its usage method. By setting a counterweight assembly within the metal frame, the counterweight ring therein can be disassembled. Thus, when the sediment is relatively soft, the counterweight ring can be not used to reduce the weight of the treatment part for easy lifting. While when the sediment has a large sand content and a large sinking resistance, the counterweight ring can be installed to increase the counterweight. The installation of the counterweight ring is also relatively simple. Just adjust the angle, push it up, and then rotate it by a certain angle to complete the installation, which is practical and convenient. Brief Description of the Drawings

Detailed Embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] The present invention provides four technical solutions:

[0033] Figure 1-3 The first embodiment is shown: An in-situ depth treatment device for river bottom sediment pollution includes a winding mechanism 1 installed on a hull and a treatment part 2 for treating river bottom sediment. The winding mechanism 1 is connected to the treatment part 2 through a pipeline. The treatment part 2 includes a metal frame 21 with an open bottom. A telescopic aeration assembly 22 is fixedly connected through the top of the metal frame 21. An exhaust vertical pipe 23 is fixedly communicated in the middle of the top of the metal frame 21. A waterproof electromagnetic exhaust valve 24 is fixedly connected to the top of the metal frame 21. A weight component 25 is arranged on the inner top of the metal frame 21;

[0034] The telescopic aeration assembly 22 includes a plurality of circumferentially distributed sleeves 221 fixedly connected through the top of the metal frame 21. A telescopic pipe 222 is slidably connected inside the sleeve 221. A first spring 226 abuts between the top end of the inner pipe 2232 and the top inner surface of the outer pipe 2231. And two sets of upper and lower telescopic aeration pipes 223 are rotatably connected between the bottom ends of adjacent telescopic pipes 222. An aeration branch pipe 224 and a bacterial liquid injection branch pipe 225 are fixedly connected inside the telescopic pipe 222. And the bottom ends of the aeration branch pipe 224 and the bacterial liquid injection branch pipe 225 are respectively fixedly connected to one end of the upper and lower layers of telescopic aeration pipes 223.

[0035] By designing the structure for inserting into the sediment for aeration and injecting bacterial liquid as the telescopic aeration assembly 22, and dividing it into multiple independently telescopic and movable parts, when it is inserted into the sediment, even if a part is inserted onto a stone and cannot descend, it will not cause the whole to be unable to descend, and other parts can still be inserted for corresponding operations, improving the adaptability of the device.

[0036] Figure 1-2 Figure 4 shows the second embodiment. The main difference from the first embodiment is that: the telescopic aeration pipe 223 includes an outer pipe 2231 rotatably connected to adjacent two telescopic pipes 222 respectively. And an inner pipe 2232 is slidably communicated between the interiors of the two outer pipes 2231. A plurality of fine holes 2233 are opened on the sides of the outer pipe 2231 and the inner pipe 2232. The aeration branch pipe 224 or the bacterial liquid injection branch pipe 225 is fixedly connected to the end of one side of the outer pipe 2231.

[0037] The bottom end of the telescopic pipe 222 is conical. The cross-sections of the outer pipe 2231 and the inner pipe 2232 are both oval pipes, which are used to reduce the resistance when inserted into the sediment.

[0038] Four layers of partition plates 26 are fixedly connected inside the exhaust vertical pipe 23. And three sealed cavities are formed between the four layers of partition plates 26. The top ends of the aeration branch pipe 224 and the bacterial liquid injection branch pipe 225 are respectively communicated with the sides of the upper two cavities. And an aeration main pipe 27 and a bacterial liquid injection main pipe 28 with bottom ends respectively communicating with the upper two cavities are fixedly connected inside the upper two partition plates 26.

[0039] The coiling mechanism 1 includes a main chassis 11. Inside the main chassis 11, there are a winch, an aeration pump, and a bacterial liquid supply pump. One side of the main chassis 11 is rotatably connected to a pulley 12 through a bracket.

[0040] The pipeline includes a coiling hose 3 threadedly connected to the top end of the exhaust riser 23. The main aeration pipe 27 and the main bacterial liquid injection pipe 28 pass through the inner part of the coiling hose 3 and are respectively connected to the aeration pump and the bacterial liquid supply pump. Reinforcing support rings 4 are evenly arranged on the surface of the coiling hose 3.

[0041] Multiple telescopic aeration pipes 223 are connected to the telescopic pipe 222, which can form an annular structure, and can thus be expanded to a certain range for microbial treatment and aeration. At the same time, the telescopic aeration pipes 223 are rotatably connected to the telescopic pipe 222 and can themselves be telescopic. Thus, they can automatically change the angle and stretch along with the telescopic movement of the telescopic pipe 222. Even if some telescopic pipes 222 are inserted into stones and have different heights relative to other telescopic pipes 222, the telescopic aeration pipes 223 can still form an annular structure. The pipes for aeration and providing microbial agents are both protected by the coiling hose 3, which is not only convenient for coiling and unwinding, but also uses the reinforcing support rings 4 outside the coiling hose 3 to provide sufficient compressive protection to ensure the smoothness of the pipes.

[0042] Figure 5 The third implementation manner is shown. The main difference from the second implementation manner is that: a conical hole is formed in the center of the bottom partition 26. Inside the bottom cavity, a plug 29 that has a gap with the side wall and can block the conical hole is slidably arranged. A second spring 210 abuts between the top of the plug 29 and the upper partition 26 above it. An exhaust port is formed on the side of the bottom cavity, and a filter cover 211 is threadedly connected to the outer end of the exhaust port. The filter cover 211 can prevent foreign objects from entering the outside.

[0043] By providing a pressure valve composed of a partition 26, a plug 29, and a second spring 210 inside the exhaust riser 23, when the air pressure inside the metal frame 21 reaches a certain pressure value after aeration, the plug 29 can be pushed open for exhaust, and at this time, external water will not enter. At the same time, since the air is in the upper layer, the turbid sewage inside the metal frame 21 will not be discharged, which can thus prevent the pollution of the outside water, reduce the leakage of the bacterial agent, and also prevent the gas from lifting the metal frame 21 and affecting the normal operation.

[0044] Figure 2 and 6The fourth implementation mode is shown. The main difference from the third implementation mode is that the counterweight assembly 25 includes a support block 251 fixedly connected circumferentially and uniformly in the middle and upper layers of the inner wall of the metal frame 21, and a positioning block 252 is fixedly connected to the top of the support block 251; the counterweight assembly 25 further includes a counterweight ring 253 that can be placed on the support block 251. A notch 254 adapted to the support block 251 is provided through the upper and lower sides of the side surface of the counterweight ring 253, and a positioning groove 255 adapted to the positioning block 252 is provided at the bottom of the counterweight ring 253 in a position offset from the notch 254.

[0045] By arranging the counterweight assembly 25 inside the metal frame 21, the counterweight ring 253 therein can be disassembled. Thus, in the case of soft bottom mud, the counterweight ring 253 can be not used, reducing the weight of the treatment part 2 and facilitating lifting. When the sediment contains a large amount of sand and the sinking resistance is large, the counterweight ring 253 can be installed to increase the counterweight. The installation of the counterweight ring 253 is also relatively simple. Just adjust the angle, push it up, and then rotate it by a certain angle to complete the installation, which is practical and convenient.

[0046] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0047] During use, the winch in the winding mechanism 1 is controlled to release the winding hose 3, so that the treatment part 2 sinks to the bottom of the water and is inserted into the bottom mud. If a part of the telescopic aeration assembly 22 is pressed, the local telescopic pipe 222 can be retracted into the sleeve 221, and the telescopic aeration pipe 223 can also be tilted and elongated, and the rest is normally inserted into the bottom mud. After that, the normal air aeration pump and the bacterial liquid supply pump can work. The bacterial liquid supply pump extracts the bacterial agent and discharges it into the upper telescopic aeration pipe 223 through the main bacterial liquid injection pipe 28 and the branch bacterial liquid injection pipe 225, and discharges it through the fine holes 2233. High-pressure air is discharged into the lower telescopic aeration pipe 223 through the main aeration pipe 27 and the branch aeration pipe 224, and discharges it through the fine holes 2233, thereby realizing aeration and microbial treatment.

[0048] Air accumulates at the top inside the metal frame 21. When the air pressure reaches a certain value, it can overcome the pressure of the second spring 210 to push open the sealing plug 29 and discharge for pressure relief from the filter cover 211.

[0049] If it is necessary to increase the counterweight, the notch 254 of the counterweight ring 253 can be aligned with the support block 251, the counterweight ring 253 is pushed to the topmost position, and then the counterweight ring 253 is rotated so that the positioning groove 255 is aligned with the positioning block 252 and then it can be put down.

[0050] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
